' `Specification of Letters Patent.

Patented June 29, 1915.

Application filed January '15, 1815. Serial No. 2,324.

T0 LZZ whom it may concern l Be it known that I, Louis LADINsKI, a citizen of the United States of America, residing in the borough of Bronx',city, county, and State of New York, have invented an Improvement in Cross-Belt Spacers, of which the following is a specification.

In many instances, in belting, as is well known, it is necessary to cross a belt, or in other words to cause the same to travel in one direction over the drivepulley, and in the opposite direction around the driven pulley. Where it is necessary to do this, both parts of the belt, at` which the samecross,

come into contact and rub against onean-A other, thereby not only causing an undue wear in the belt but also unnecessarily wasting the power applied in driving the machine.

rIhe object of my inventionis the provision of a simply constructed apparatus for preventing those parts of the cross belt from coming in contact with one another, where the same cross, thereby preventing undue wear in the belt, and also in view of the comparatively small friction between onev part of the belt and the contact device employed to separate the same from the other part of the belt, there is, in the employment of my belt spacer, a material saving in the power employed to drive the machine in which the said belt spacer is used.

rlhe construction of my improved cross belt spacer will be hereinafter more particularly described.

In the drawing, Figure 1 is an elevation of an apparatus tted with my improved cross belt spacer. Fig. 2 is a plan of the support and adjustable bracket connected therewith. Fig. 3 is a side elevation of these parts, including the adjustable arm carrying the belt contact member, and Fig: 4 is an elevation of the offset end of the arm in which I employ a pulley to contact with one member of the belt. ff In the drawing, I have illustrated my inventionv as applied to a sewing machine, although, as will be understood, its application is not so limited, inasmuch as ity may be employed, when properly constructed, in any place where it is necessary to cross a belt.

In the drawing, 10 indicates a support suitably connected to the base of a machine.

11 indicates the frame upon which the top 12 or table of the machine is connected.

bearing 19in which the shaft of a pulley 2Ok is journaled. As indicated, the pulley 17 is a drive pulley, and the pulley y 20 a driven pulley( This driven pulley 20 is also adapted to receive a belt 22, employed to drive the machine, as will be understood.

21 indicates the belt employed to drive the pulley 20 from the pulley 17, and, as shown, this belt is crossed.

In a suitable position on the support 10, there is provided a projection 23. Adjacent its extremity on one side thereof, there is a f recess 24 in this projection 23. I also employ a bracket 25, the arms 26 and 28 of which are at right angles to each other. The

arm 2G is adapted to fit and slide within the recess 24, and may be adjusted to position therein toward and away from the drive pulley 17, and fixed in such adjusted position f by means of a bolt 27, which is passed through suitable slots provided for this purpose in either the arm 26 or the projection 23, or in both of these members. @ne face of the arm 2S of the bracket 25 is also recessed, as is indicated at 29, in order to receivethe arm 31 of the member 30. rIhis is adjustable to position therein and when Aso adjusted may be fixed in place by means of a screw 34, which passes through the slot 33 in the arm 31 and turned down into a tapped opening provided in the arm 28. The arm 32 of the member 30 is also preferably at right vangles to the arm 31 thereof, and at its free end is provided with lugs 35. These are olfset or placed at an angle to the arm and are preferably parallel to one end and provided with a pin or arbor 36, upon which, between the lugs, is mounted a pulley 37.

From the foregoing description, it will `be apparent that the bracket 25 may be adjusted toward and away from the drive pulley and fixed in place by the bolt 27, and that the member 30 may be adjusted toward and away from one4 part of the belt 21, and by the set screw 3l. fixed in the necessary posisaving in the power necessary to drive the tion toy maintain that portionr of theY belt with which the pulley 37 contacts, away from the other portion of the beltV at' those portions of the belt at Which the same cross.

' pulley 37 and that portion of the belt which contacts With the saine, there is a material machine.
